# Choosing best in class eor software for mobile app developers
What should a busy buyer check before approving a hire?
Ask for the proposed employment agreement and service agreement before approving the developer's start date. Give your legal team the actual work location, role, and expected working pattern. Give security a list of the systems the developer will need.
A software demo can show how someone submits leave or downloads a document. Your review also needs to establish who signs that document and who must act when something goes wrong.
For a React or React Native hire, work through a realistic first assignment. Suppose the developer will fix a login flow, inspect crash reports, and publish a test build. Identify the code, credentials, and user information each task needs. Then assign someone to approve that access.
Use this approval checklist:
- Identify the legal entity that will employ or contract with the developer.
- Have local counsel review the proposed arrangement against the actual work.
- Trace code ownership from the developer through any intermediary to your company.
- Approve the payroll budget and ask how changes reach your invoice.
- Name the people responsible for access, incidents, and departure.
Keep the answers with the signed agreements. A salesperson's explanation can help you find the right clause, but your team should review the clause itself.
If you plan to hire a React JS developer for ongoing product work, describe that work plainly. Include expected hours, reporting lines, release duties, and any outside-work restrictions you intend to request. Ask counsel to assess those facts before choosing a contract label.
Make the start date depend on completed approvals. Recruiting progress and readiness to handle customer data are separate decisions. A developer can complete interviews while your team finishes the employment and access review.
Set a clear rule for unresolved items. For example, an unsigned IP agreement should keep repository access pending. An unanswered payroll question should go to finance with an owner and due date. Record who can approve an exception and what work may begin under it.
Give the hiring manager a short status sheet showing each approval, its owner, and the document that supports it. That sheet should let a replacement manager understand the arrangement without replaying sales calls.
What do the rules say about classification and local costs?
The US Department of Labor says employers must determine whether a worker is an employee under the FLSA. It describes misclassification as treating an employee as an independent contractor. For a developer working abroad, obtain a local labor-law assessment rather than treating US guidance as the governing test. US Department of Labor
Give the reviewer a description of how the engagement will work. Include who sets the schedule, who directs tasks, and whether the work has a defined end. Ask what changes would require another review.
Tax paperwork deserves its own review. The IRS describes Form W-8BEN as a certificate of foreign status for US tax withholding and reporting. Its instructions address giving the form to a withholding agent or payer in the stated circumstances. Ask your tax adviser which forms apply to your payment arrangement. IRS guidance on W-8BEN
For budgeting, request a country-specific payroll schedule. The examples below show obligations to discuss with the proposed employer. Have that employer explain how each relevant amount appears in your quote.
| Country | Obligation to discuss | Question for the quote |
|---|---|---|
| Mexico | Article 87 provides an annual aguinaldo of at least 15 days of salary, payable before December 20. Ley Federal del Trabajo | How is aguinaldo funded during the engagement, including a partial year? |
| Colombia | Article 306 provides prima de servicios equal to 30 days of salary per year, recognized in two payments. Código Sustantivo del Trabajo | Does the quote include prima, and how are the payments reconciled? |
| Argentina | Article 122 provides two SAC installments, due June 30 and December 18. Ley de Contrato de Trabajo | How will salary changes affect the SAC calculation and your invoice? |
| Brazil | Lei 4.090 provides a December salary bonus, calculated at one-twelfth of December remuneration per month of service. Lei 4.090 | How does the monthly quote account for the statutory bonus? |
| Costa Rica | Ministry guidance quotes the annual aguinaldo benefit as equivalent to a month of salary. Ministerio de Trabajo | What earnings enter the calculation, and who approves the payment? |
Other payroll items need their own lines. Colombia's article 249 describes cesantías based on a month of salary per year of service, with proportional treatment for a fraction of a year. Ask how the employer calculates and administers this obligation. Código Sustantivo del Trabajo, article 249
Mexico's article 80 sets a vacation premium of at least 25% of the salary corresponding to the vacation period. Ask whether the proposed monthly charge includes that premium and how leave is recorded. Ley Federal del Trabajo, article 80
Request a worked payroll example using the proposed salary and start date. It should show what the worker receives, what the employer pays, and what your company owes. Ask finance to reconcile that example with the contract.
Have finance distinguish recurring charges from amounts held for later payment. Ask what happens to any unused balance when the engagement ends. Record the invoice currency, exchange-rate method, and approval process for changes. Use the same assumptions when comparing quotes.
Also request an exit estimate for the proposed arrangement. Have the provider state its assumptions and identify who approves the final calculation. Avoid building a termination budget from a single statutory formula without reviewing the circumstances.
Ask for separate examples for a resignation and an employer-initiated departure. Your team needs to see which steps and costs depend on the reason for leaving. Keep those examples as planning tools, and request a fresh calculation when an actual departure occurs.
How do nearshore and Latin American hiring models differ?
Choose the model by deciding which responsibilities your company can perform. Then check that the agreement assigns the remaining work to a named party.
An EOR arrangement is worth assessing when you have selected a developer and need a local employer. Ask which entity signs the employment agreement and which entity signs your service agreement. Have counsel review the relationship between those contracts.
A recruiting agency addresses the search for a candidate. If you use that model, decide how employment will work before making an offer. Assign payroll and local employment duties to your own team or another contracted party.
Direct employment puts the proposed employment relationship with your company or its local entity. Before choosing it, have your internal team confirm that it can operate payroll and manage the relevant employment process. Include ongoing administration in the decision, alongside setup.
For a managed nearshore arrangement, review the exact service scope. Ask who finds candidates, who contracts with them, and who handles payroll. Confirm whether your engineering team directs daily work or buys a defined delivery outcome.
| Model under review | Responsibility to settle before signing | Evidence to request |
|---|---|---|
| EOR | Legal employment and the division of duties with your team | Named employer, worker agreement, service agreement |
| Recruiting agency | Who takes responsibility after candidate selection | Search terms and a separate employment plan |
| Direct employment | Your company's capacity to operate local employment | Internal approvals and local payroll process |
| Managed nearshore service | Search, employment administration, and daily management | Written scope and responsibility schedule |
| Independent contractor | Whether the actual engagement supports that arrangement | Local legal assessment and agreed scope of work |
For any model, ask who owns decisions about leave, performance concerns, and ending the relationship. A shared responsibility should still have a named contact on each side.
Test the arrangement with an ordinary problem: a developer needs leave during a planned release. Who confirms the employment entitlement? Who changes the sprint plan? Who tells payroll? Record the handoffs before the first conflict.
Then test a departure. Your team needs to know whom to contact before telling the worker that the engagement will end. Security needs a coordinated access plan. Finance needs a calculation it can approve.
Review changes during the engagement as well. Ask what happens if the developer moves to another country or takes on release duties outside the agreed schedule. Require an advance review of the proposed change. Update the employment assessment and access plan where needed before treating the new arrangement as routine.
What should you ask a provider about IP and data access?
Bring engineering, legal, and security into the same review. Give them the proposed agreements and a short description of the developer's first project. Ask the provider to answer in writing where its responsibilities begin and end.
Request the complete code ownership path
Ask counsel to follow the rights in the work from its creator to your company. Review both the worker agreement and your contract with the provider. Check whether the documents describe the same work and parties.
For a React engagement, ask about application code, reusable components, tests, and design files. For React Native, include native modules and release configuration. List the deliverables your team expects to retain.
Ask how the agreement handles code the developer already owns. Establish a review process for introducing that code into your product. Do the same for third-party packages and assets, with someone assigned to review license terms.
Ask whether anyone else may contribute to the work. If substitutes or subcontractors are permitted, request the approval process and the documents covering their contributions. Your engineering lead should know who can access the repository.
Portfolio review needs a boundary too. Tell candidates not to share a previous client's private repository or customer records. A discussion of architecture and tradeoffs can use public or candidate-owned examples.
If you commission an assessment, write down payment and ownership terms before work starts. Use a task that avoids production access. Decide in advance whether the submission is only for evaluation or may become part of the product.
Set rules for AI coding tools before the developer uses them on company work. Specify which accounts and tools are approved and what code or data may be submitted. Ask the engineering lead to review generated changes through the same process as other contributions. Have counsel assess any tool terms that affect your intended use.
Define access around the assigned work
Create an access list for the role before onboarding. Include repositories, issue tracking, cloud environments, and any mobile release tools. For each system, name an approver and describe the access needed.
Start with company-controlled identities and require multifactor authentication. Ask security to approve device requirements and credential storage. Avoid sending shared passwords in onboarding messages.
Use test data where practical. If the developer needs customer information, document the reason and have the responsible team approve the access. Ask privacy counsel to review any required terms for cross-border access.
Include crash reports, support tickets, and screenshots in that review. Ask the project owner to inspect sample records before granting access. If a task only needs an error message, prepare an example that excludes unrelated customer details.
For mobile work, decide who controls release credentials and signing materials. Separate permission to prepare a build from permission to publish it where your workflow supports that distinction. Name the person who approves each release.
Have the provider explain what evidence it can give you about its own controls. Ask who operates each control, how exceptions are approved, and how your team receives incident notices. Request the terms that support those answers.
Walk through an incident and a departure
Use a concrete incident during the review: a developer loses a laptop that had repository access. Ask who receives the report, who disables access, and who checks whether credentials need to change.
Record contact details and the agreed escalation route. Your team should know how to reach someone outside the usual meeting schedule. Ask how the provider documents its response and shares the outcome.
For departure, assign an owner to each task:
- Coordinate the employment process with the employer.
- Transfer open work, code, and release notes.
- Remove accounts and revoke credentials at the agreed time.
- Recover equipment or confirm its approved disposal.
- Review retained files and obtain the agreed deletion confirmation.
Check service accounts and automation created during the engagement. Have an internal owner take responsibility for them before the developer leaves. A release pipeline should remain manageable after a personal account closes.
Test the handover by asking an internal engineer to run the documented build and locate the release settings. Resolve any dependence on the departing developer's personal credentials before closing the handover. Record unfinished work so the next engineer knows which changes are ready for review.
Keep the completed checklist with the engagement record. Ask the provider which records it retains and how you can obtain them if a dispute arises.
Make the demo prove the proposed workflow
Ask the salesperson to demonstrate your hiring scenario. Follow the worker from contract preparation through payroll approval and departure. Have your reviewers compare the screen actions with the duties in the service agreement.
Try an exception as well. Ask what happens when the proposed start date changes after documents are prepared. Then ask how an approved salary change reaches payroll and your invoice.
Export a sample record during the demo. Confirm that your team can retrieve the documents it needs without relying on a former account administrator. Ask what access remains after the service ends.
Have the provider show how permissions differ between an engineering manager and a payroll administrator. Check who can view personal documents and change payment details. Ask how approvals and edits appear in the activity record, and have your reviewers inspect an example.
What should you confirm with Opus?
This site is an Opus-owned reference; recommendations are editorial.
Opus states: "Opus charges one flat monthly rate per hire. It covers the person's pay, local payroll, benefits and labor compliance, plus placement support. There is no separate recruiting fee. The rate depends on role, seniority and location."
Published dollar rates: Not published. Request a written quote for your role and location. Ask how the agreement handles salary changes, expenses, and costs when the engagement ends.
Opus states: "The client chooses the finalist and manages day-to-day work." Build your internal approval process around that division. Name the engineering manager who will assign tasks and approve access.
Talk to Opus about a React role.
Bring the proposed role, work location, and first project to that conversation. Ask for the contracting entity and the agreements your reviewers will receive. Request a written responsibility schedule for employment administration and your team's duties.
Opus states: "Every placement carries a lifetime replacement guarantee with no cap and no time limit." Review the guarantee alongside the employment and service agreements. Ask how a replacement search affects the existing engagement, payroll, and handover.
Use the same IP review you would use for any hiring model. Ask counsel to confirm the path from the developer's work to your company. Have security approve the access plan before provisioning accounts.
Before signing, collect the quote, reviewed agreements, payroll assumptions, and named contacts in the hiring record. Give the engineering manager a start checklist that includes the remaining approvals. Confirm the start date when those owners are ready.

Questions & answers
How should we assess best in class eor software for mobile app developers?
Start with the proposed employer, country-specific employment documents, IP terms, and access controls. Ask the provider to demonstrate onboarding and departure using your hiring scenario. Compare software after legal, finance, and security have reviewed those details.
Does the best React developer resume prove a hire is compliant?
A resume helps assess experience. Review the employment arrangement separately, including the developer's work location, proposed contract, and actual duties. Ask local counsel to assess classification before work begins.
How should we review a React developer portfolio without requesting confidential code?
Ask for public work, a candidate-owned example, or a discussion of technical decisions without private code. Use synthetic data for an assessment. Agree on payment and ownership terms before commissioning work you might use.
What IP documents should we request for a nearshore React hire?
Request the worker agreement and the provider agreement. Have counsel trace how rights in the developer's work reach your company. Ask about pre-existing code, third-party licenses, subcontractors, and obligations after the engagement ends.
Should a React Native developer receive production access on the first day?
Grant access based on assigned work and approved security requirements. Start with a development environment and test data where practical. Require explicit approval for production systems, release credentials, and customer data.
Which tools should top React developers use for secure onboarding?
Use company-controlled accounts, multifactor authentication, approved credential storage, and a documented access request process. Ask the provider which controls it manages and which your engineering team must operate.
Does an EOR replace our engineering manager?
Define employment administration and engineering management separately in the agreement. Assign responsibility for task direction, code review, working hours, leave coordination, and performance concerns before the developer starts.
What should we check before hiring a React developer in Bihar?
Ask for the proposed legal employer and an employment review for India. Confirm the developer's actual work location and agreed schedule. Have local counsel review the arrangement rather than reusing a Latin American contract.
Does a W-8BEN establish contractor status?
The IRS describes W-8BEN as a certificate of foreign status for withholding and reporting. Have the employment arrangement assessed separately; collecting a tax form should not be your classification review.
What should a Latin American developer's departure plan include?
Assign owners for the employment process, final payroll, code handover, account removal, and equipment return. Ask the provider for a country-specific cost calculation, and have engineering document when access ends.
