StitchInvoice Home

For agencies & studios

Several active clients. One place that keeps them straight.

Project quotes that need sign-off, retainers that bill on their own schedule, and the client-specific rules that come with each account — kept in one workspace instead of scattered across templates and reminders to yourself.

The problem

More clients means more ways for billing to fall through the cracks.

•

A handful of active clients at once, each with a different scope, cadence, and set of billing rules

•

A quote that needs sign-off before a project team starts work, not an assumption that it will happen

•

Some clients billed per project, others on an ongoing retainer, tracked in two different places

•

A billing correction on an already-sent invoice, with no clean way to fix it without editing history

•

No shared picture of which clients are current, which are late, and which need a nudge this week

How StitchInvoice approaches it

Project work and retainers, without the account-by-account guesswork.

Quotes clients approve

Scope a project as a quote and get it approved with a typed signature from the client's own link, before the team starts billable work.

Recurring invoices

Ongoing retainers and maintenance contracts bill automatically on their own schedule, alongside project work billed one-off.

Credit notes

Correct a billing error or apply a goodwill adjustment with a proper credit note that references the original invoice — never by editing a document the client already has.

Requirements memory

PO numbers, specific approvers, and billing formats stay attached to each client account, so account switches on your team don't mean relearning the rules.

Payment Intelligence

On-time rate and outstanding balance per client, so a slipping payment pattern is visible before it becomes a cash-flow problem.

Client portal

Each client gets a link to review and pay what they owe — useful when a project has multiple stakeholders on the client side, not just one contact.

What StitchInvoice is not

Worth being upfront about.

Not project management software — no task boards, timelines, or resourcing tools
Not built for internal team billing or multi-department cost allocation
Not a CRM; client details here are billing-focused, not a full sales pipeline

Questions

Common questions from agencies.

Can we bill project work and retainers from the same place?

Yes. A fixed-fee project converts from an approved quote into a one-off invoice, while retainer clients can be set to bill automatically on a recurring schedule — both live in the same client record.

How do we correct an invoice a client has already received?

Never by editing the sent document — that version is the record both sides rely on. A credit note references the original invoice and corrects the balance without erasing what actually happened.

Does a quote need client sign-off before work starts?

That's how it's designed to work: the client approves the quote with a typed signature from their own link, and it converts directly into the first invoice once accepted.

Can different clients have different billing requirements?

Yes. PO numbers, approver contacts, CC lists, and payment terms are all saved per client, and applied automatically on every future document for them.
