Bookkeeping built for a contractor, not a shop: every transaction tagged to a job, monthly P&L by account and by job, a 13-week cash-flow forecast that rolls forward, mileage, and a tax set-aside figure for your accountant.
Excel · Google Sheets
Bill by percentage complete like the big contractors do: schedule of values, retainage, previously billed, this period - and a progress invoice that fills itself when you type the period number.
Excel · Google Sheets
A real schedule, not a drawing: tasks linked by predecessors, durations in working days, milestones, and a Gantt chart that redraws itself when a date moves.
Excel · Google Sheets
Takeoff by area and assembly with waste factors built in, imperial/metric conversions, and an order log that shows what's ordered, what's delivered and what's still missing.
Excel + Word
Stop losing money on "small changes": log every change with cost and days impact, keep a running contract sum, and print a signable change-order form that fills itself.
Excel · Google Sheets
Every sub and supplier in one place - with insurance and licence expiry warnings before an inspector asks, a three-bid comparison that highlights the low bid, and payments tracked per vendor.
Excel + Word
The paper trail that wins disputes: weather, crew, hours, work done, deliveries and incidents for every day, a one-page printable daily report, and a punch list with sign-off.
Word · Google Docs
A proposal that reads like a serious contractor wrote it: scope, exclusions, pricing table, payment schedule, schedule, terms and an acceptance block - plus a one-page quick quote for small jobs.
