IT and Software Company Software: Milestones, Retainers and Scope Creep

The quotation is the scope document

A client asks for a website, an app or a custom module. The quotation must say what is included, what is not, how many revisions, and when payment is due. If the scope lives only in an email, every change becomes an argument.

Keep the accepted quotation linked to the project. When the client asks for an extra report, issue a variation or a new quotation instead of quietly absorbing it.

Invoice at milestones, not at hope

Advance, design approval, delivery and support are natural milestones. Each one should release an invoice against the project. The project view should show billed, received and still-to-bill, so the team knows whether the next milestone is funded.

Retainers are recurring revenue

Hosting, maintenance and support renew monthly or yearly. These are not new sales each time; they are recurring invoices with a start date and a next-date view. Missed renewals are pure loss because the cost of service continues.

Costs before the invoice

Domain, hosting, third-party API, contractor payment and software licences are project costs. If they sit in a general expense list, the project looks profitable until the renewals arrive. Tag each cost to the client or project and read the margin before promising a discount.

Deliverables and handover

A project is not finished when the code runs; it is finished when the client accepts it. A task list with owners and a final handover note protects both sides. The public invoice link also gives the client a clean record without asking for a PDF on WhatsApp.

Audit one project

Pick a live project and check four numbers: quoted value, billed so far, costs so far and hours promised. If any one is missing, the project is being run from memory.
