Describe the goal, users and workflow. Never submit passwords, tokens, customer records or private credentials.
Payment and delivery
Scope first.
Invoice second.
Payment last.
StackPayback separates custom services from future downloadable products so every buyer can see what they are paying for, how delivery works, and which terms apply before money changes hands.
Custom-service flow
Four clear stages from request to handoff.
A predictable sequence protects the buyer, the project, and the delivery timeline.
Approve the quote
Confirm deliverables, exclusions, price, milestones, timeline, revisions and handoff terms in writing.
Verify billing details
Match the legal provider, bank beneficiary, currency, amount, reference, and milestone shown on the accepted invoice.
Build and hand off
Scheduling starts after the agreed payment is confirmed. Delivery follows the milestones and handoff method in the quote.
Before paying
Your quote and invoice must show every critical detail.
- Legal provider and client reference
- Approved service scope
- Price, currency, and taxes
- Bank beneficiary and reference
- Payment milestones
- Revision allowance
- Delivery method and timing
After confirmation
Delivery matches the approved scope.
Custom bots are not instant downloads. The accepted quote can include a private repository, deployment handoff, documentation archive, or files sent to the buyer's confirmed email.

Future downloadable products will use a verified checkout provider that can issue receipts and release the correct file after successful payment. No product is presented as an instant purchase until that checkout is live.
Buyer safety
Stop if the payment details change unexpectedly.
Verify billing instructions against the accepted quote through the agreed owner contact before sending money.
- Confirm the legal provider and full bank beneficiary details.
- Use the project or invoice reference shown in writing.
- Keep the invoice and transfer receipt as payment evidence.
- Never make a second transfer because of an unsolicited “account changed” message.
