Built from real work

Designed around CJN Solutions’ own finance work

Our own quotations, contracts, milestones, invoices and withholding certificates are the brief this system was designed around — not invented examples.

Quotation

Scope, milestones, acceptance

Contract

Payment terms, client PO number

Invoice

Issued from an accepted milestone

Receipt

Matched to the actual payment

Withholding certificate

Form 50 Tawi — every one collected

Five documents that must chain together, with matching numbers on every one

What it covers

What general accounting software does not know, and project firms face every month

Projects, contracts and milestones

Milestones with amounts, planned billing dates and per-client payment terms
PO numbers and the client’s billing cycle
One-click invoice from a milestone

Sales documents you can audit

Sequential numbering — no gaps, no duplicates
Immutable once issued; replacements carry a reason
Signed files stored with every document

Withholding tax — received and issued

Every receipt paired with a certificate: pending, received or mismatched
Amount checked against payment × rate
Reminders when cash has arrived but the certificate has not

Receivables and billing cycles

Ageing by each client’s real terms
Reminders before the client’s billing window
Which milestones are invoiced, which await acceptance

Cost and margin per project

People, cloud and subcontractor costs tied to the project
Margin visible only to those who should see it
Actuals against the estimate in the quotation

Cash flow and tax calendar

Forecast from clients’ real payment dates, net of withholding
Monthly and annual filing deadlines
Year-end withholding-credit summary for your accountant

Who it is for

Businesses whose revenue arrives in milestones, not daily sales

Not an accounting package and not a replacement for your accountant — it feeds sales documents and receipts to the accounting firm and software you already use.

Consultancies and software teams

Paid in milestones, 3% withheld at source, and every certificate needed for the year-end tax credit.

Agencies and design studios

Overlapping projects, each client with its own billing cycle and terms.

Systems and installation contractors

Subcontractors to withhold from, and certificates to issue, every month.
