Build vs buy: payment layer checklist

• Futurify Team

For platform CTOs and PMs with a cutover date.

Use this before you pick a vendor logo. It forces the ownership and operating questions into the open.

Before the call

  • Platform / product name
  • Cutover date
  • Processor you are leaving (if any)
  • Rails on day one (cards, EFT/PAD, Interac e-Transfer, other)
  • Who owns the date (name + role)
  • What “done” means on day one (one sentence)

Ownership score

Answer yes / no / unclear:

  1. Will we hold the processor contract after go-live?
  2. Must the layer run in our perimeter?
  3. Do we need a second processor without another discovery project?
  4. Do we keep payments margin (no vendor share of spread as the core deal)?
  5. Do we need an exit that leaves us with instance, config, data, and event log?

Rule of thumb: three or more yes → shortlist a client-owned layer. Three or more no → hosted orchestration may fit.

Operating checklist

Ledger and reconciliation

  • Insert-only posting where cash moves
  • Idempotent retries
  • Exceptions queue with a named owner
  • Finance export that replays to provider settlement

Cutover

  • Day-one scope written (what stays live)
  • Dual-run or hard cut named
  • Rollback condition written
  • Support ownership for week one

Commercial

  • Fixed-price Build vs T&M named
  • Run / managed ops priced per account (or explicitly declined)
  • Referral / integrator fees disclosed before a processor is recommended
  • No custody / no PSP registration required from the software vendor

Decision

If your constraints are…Shortlist…
SaaS speed, card multi-PSP, fine with vendor cloudHosted orchestration vendors
Perimeter, keep contracts/margin, dated cutover, reconciliationClient-owned ISV layer (Futurify shape)
Single processor forever, strong internal payments teamIn-house against one provider (accept future migration cost)
