Building the Product

What's a fair way to structure a milestone-based contract with a dev agency?

A starting point

Tie payments to working, demonstrable milestones you can actually see in a browser, not to hours logged or vague phases like "backend complete". Keep the first milestone small and cheap so you can test how the agency works before you are deep in. Hold a meaningful final payment (say 20 to 30 percent) until after you have used the delivered build yourself for a week.

Why we picked it This is the clearest walkthrough of turning a build into payment-linked milestones (prototype, then beta, then launch), where cash only moves after a deliverable passes acceptance. It is written for founders, not lawyers, and includes a real case where breaking a project into five milestones let the founder prune features at each gate and cut actual spend by about a quarter. It also compares milestone-based against fixed-price and time-and-materials so you can tell when each one actually fits.

Software & Mobile App Development Contract for Startup Founders

From Ptolemay by Olga Gubanova ~20 min read

  • Tie each payment to a concrete deliverable that passes acceptance, not to a calendar date, so you never pay ahead of working software.
  • Milestones double as decision gates: you can re-scope or drop low-value features between them instead of being locked into the original plan.
  • Milestone-based is not always right. Fixed-price suits a frozen spec, and time-and-materials suits an MVP that is still shifting.

Why we picked it A milestone contract can still leave you without your own code if IP ownership is fuzzy, and this guide is the plain-language checklist for closing that gap. It spells out the pieces that actually secure ownership: a work-for-hire or invention-assignment clause, an NDA, non-compete terms, and limiting what you disclose. Written from a vendor that outsources at scale, so it reads as practical rather than legal theory.

A Practical Guide to Protect Your Source Code IP When Outsourcing

From Clarion Technologies by Clarion Technologies ~10 min read

  • A milestone contract is not enough on its own: without an explicit work-for-hire or invention-assignment clause, the developer can retain ownership of what they build.
  • Make ownership reach the individual developers and subcontractors, not just the agency, so no one down the chain can claim the code.
  • Pair the ownership clause with an NDA and share only what the work requires, so sensitive logic never leaves your control.

Why we picked it Most contract templates online are US-shaped, and this one is genuinely built for the Indian context: it covers IP assignment under the Copyright Act 1957 (India has no automatic work-for-hire, so the assignment language matters), DPDP Act data handling, milestone payment schedules, and a source-code escrow clause. For a founder building outside the big startup hubs without a lawyer on retainer, it is a concrete starting point that already speaks to Indian law. Treat it as a draft to adapt, not a signed document, and have counsel review the final version.

Software Development Agreement Template (India)

From Contract Shield by Contract Shield Downloadable Word template

  • In India the client owns the code only on full payment and only with explicit IP assignment language, since there is no automatic work-for-hire doctrine.
  • It bundles the parts a milestone contract needs: payment schedule, a 30-day acceptance window, and 90-day bug support.
  • It adds India-specific pieces most global templates skip: DPDP Act data security and an escrow arrangement if the developer goes insolvent.
