“The PDF quotes look so professional. Clients actually comment on them. Worth every penny.”
— Sarah M., Plumbing & Heating
The problem
Plumbing jobs are easy to underprice when you’re quoting from memory
Quoting bathroom installs from rough mental estimates. Material costs that vary by supplier and are impossible to keep current in a spreadsheet. Multiple quote revisions when scope changes. Domestic customers who expect a written, professional quote before they commit. And labour for difficult access situations that never quite makes it onto the quote. CostForge was built to fix exactly this.
The solution
Built for the way plumbers actually price work
Nested Line Items
Break down a bathroom install: suite supply, tiling, pipework, waste, and labour — each item costed separately, rolling up into a clean total your client can read.
Staff Hours & Labour Costing
Set your own hourly rate. Enter hours per item and CostForge calculates the cost instantly. Show it or hide it from the client — your choice.
Multiple Jobs Per Client
Regular clients with a boiler service, a new bathroom, and extension heating — all tracked under the same client profile. Nothing gets mixed up.
Custom Branding
Your logo and colours on every quote. Domestic clients remember the professional ones — and recommend them to their neighbours.
VAT Support
VAT-inclusive or VAT-exclusive totals, with your own tax label. CostForge handles the maths so your quote is always correct.
