The verdict in three sentences
Excel is free but costs you hours and lost contracts: broken formulas, stale prices, late bids. Custom estimating software (5,000,000 to 16,000,000 FCFA) integrates a price library and quantity takeoff, halving quote production time. The real stake is not software cost but the bids won thanks to faster, more reliable responses.
FCFA budget for BTP estimating software
Here are 2026 orders of magnitude for a construction firm, from estimating alone to full system.
| Module | 2026 budget (FCFA) | Timeline |
|---|---|---|
| Custom estimating software | 5,000,000-16,000,000 | 3-5 months |
| Price library + quantity takeoff | 2,000,000-4,000,000 | 4-6 weeks |
| Site tracking module | 3,000,000-6,000,000 | 6-10 weeks |
| Annual maintenance | 12-15 %/year | recurring |
| Team training (estimators, quantity surveyors) | 400,000-1,000,000 | 1-2 weeks |
| Offline mode (field) | 1,200,000-3,000,000 | 3-5 weeks |
The price library is the core of the system: it centralizes your unit prices (materials, labor, subcontracting) and updates, avoiding quotes based on stale prices. Integrated takeoff removes re-entry and makes quantities reliable.
Excel vs estimating software: the time calculation
| Criterion | Excel | Custom software |
|---|---|---|
| Quote production time | 6-12 h | 2.5-5 h |
| Price reliability | risk of obsolescence | up-to-date library |
| Quantity takeoff | manual | integrated |
| Bid responses | limited | +25 % response rate |
| History and versions | scattered | centralized |
| Quote time gain | — | 40-60 % |
A firm producing 15 quotes/month at 8 h each spends 120 h/month on estimating. A 50 % gain frees 60 h/month, nearly a half-time estimator redeployed to more bid responses.
Mini case study
Ousmane runs a 25-employee construction firm. His quantity surveyors produced 15 quotes/month in Excel, at 9 h each on average, with recurring price errors. He invests 11,000,000 FCFA in custom estimating software with a price library and integrated takeoff, plus 2,500,000 FCFA for a site-tracking module. By cutting quote time 55 % (from 135 h to 61 h/month) and responding to 25 % more bids, he wins 3 extra contracts over the year, for estimated additional revenue in the tens of millions of FCFA. Estimated software payback: under 18 months.

Why leave Excel for estimating software?
Excel shows its limits as volume grows: broken formulas, stale prices, no reliable history. Custom software centralizes the price library, integrates takeoff and halves quote production time.
What is a price library?
A centralized base of your unit prices (materials, labor, subcontracting) you update and reuse in each quote. Budget 2,000,000 to 4,000,000 FCFA to build it and integrate takeoff.
How long to build the tool?
From 3 to 5 months for custom estimating. The price library and takeoff add in 4 to 6 weeks, then the site-tracking module in stages.
Is offline mode useful for takeoff?
Yes, on no-network sites, offline field takeoff (1,200,000 to 3,000,000 FCFA) lets you capture quantities on site and sync later, avoiding re-entry at the office.
What impact on bids?
Faster, more reliable quotes let you respond to more bids, with an observed gain around 25 % in response rate. Each contract won quickly pays back the investment.
