Software for Construction Companies
Custom-built construction management platform shaped around how Bulgarian contractors actually work: multiple sites at once, subcontractor contracts, bill of quantities (BOQ), material deliveries, site diary and real budget against plan. One source of truth — from the office to the formwork.
What our software for construction companies covers
Site management
Map of every active site with stage, responsible manager, deadline and current completion. Switch between ten sites without opening ten spreadsheets.
BOQ and tendering
Bill of quantities with a position library, labour and material rates, markup and VAT. Import from tender documentation, export back to the investor in standard format.
Subcontractors and contracts
Subcontractor registry with scope per site, contract value, advance payment, retention and monthly progress invoices. The system remembers every record so your project manager does not have to.
Materials, reservations and deliveries
Request from site → approval → purchase order → delivery signed off by the foreman. Reserved quantities cannot be requested twice. Zero double ordering.
Site diary and photo log
Foremen report completed work and hours from a mobile app, attach geotagged photos. Photos are grouped per BOQ line, never lost in chat threads.
Stage invoicing (act 19)
Construction stage invoicing — known locally as act 19 — generated automatically from quantities reported in the site diary, with direct reference to BOQ lines. The investor invoice flows from the same data, no retyping.
Who it fits
Utility and energy contractors
Linear sites along a route, large subcontractor pools for excavation and insulation, invoicing to utility holdings in a strict format. The system models linear kilometres and nodes as separate sites.
General contractors
Residential buildings, offices, refurbishments. 5 to 20 concurrent sites, each with its own BOQ, subcontractors and crews. Software for construction companies at this scale shows budget against actual cost in real time, not at year end.
MEP and installation firms
Electrical, HVAC, fire systems, low-voltage. Short sites, fast turnover, materials per spec. Software for construction companies in this niche keeps focus on installer hours and just-in-time deliveries.
How we build it
We do not resell someone else's SaaS. We build your own software for construction companies on a proven stack: PostgreSQL for data, S3-compatible object storage for site photos, Next.js for the web admin, native Android for the on-site app — works offline and syncs when connectivity returns.
We start with one to two days on site, watching how the foreman reports, how the surveyor builds BOQ, how the office processes deliveries. From that map we lock the MVP scope for phase one — usually sites, BOQ, materials, diary, stage invoicing and project cost control. BIM-friendly integration ships in later sprints.
We integrate with accounting tools, electronic invoicing, bank statements for automated subcontractor payments. Standard BOQ import keeps you compatible with investor formats. See how we approach mobile app development and custom ERP development.
Go-live is staged: one pilot site first, then the whole company. SLA-backed support follows. The system is yours.
Why Saitami for your construction ERP
Material overspend
Average reduction within 4-6 months — real client data from general contractors, measured against BOQ standards.
Faster stage invoice close
Achieved by auto-filling from the site diary with direct BOQ references. No retyping, no waiting for the foreman's notebook — exactly why software for construction companies is worth building in the first place.
Starting investment
Fixed price for the MVP phase. No per-user licensing, no hidden subscription. You own the system outright.
Construction company software often runs alongside an ERP system for construction and SaaS platform development if you plan a white-label offering. See also our custom software development.
Frequently Asked Questions
Is the software suitable for a company with 5 sites?
Yes, this size is the sweet spot for the €5,800 MVP scope. You get sites, BOQ, subcontractors, materials, site diary and stage invoicing without bloated modules that overwhelm a site manager. Half a day of training is enough for foremen, and the office leaves Excel behind within the first week.
Can it track crew productivity?
Yes, and this is one of our favourite dashboards. The system collects reported hours per crew against BOQ standards, calculates variance per line item and shows which crews work over or under norm. Monthly history means that during your next tender you negotiate with real numbers, not gut feel. Works for in-house crews and subcontractors alike.
Does it support the Bulgarian act 19 stage invoice?
Yes, act 19 is a first-class document, not a side PDF template. It is generated from quantities reported in the site diary, referenced back to BOQ positions, with running totals and remaining balance. Export is to Word or PDF for investor signature. Custom investor templates are supported.
How much does software for construction companies cost?
Pricing starts from €5,800 for an MVP in a small firm with up to 5-7 sites and lands between €15,000 and €36,000 for a mid-size contractor with subcontractor networks and accounting integration. Pricing is fixed against the agreed scope, paid in milestones, no per-user fees. Support is a separate SLA contract.
Ready for control over every site?
We come to your site, walk through your real process and leave you with a concrete phase-one plan for your software for construction companies — fixed price, fixed timeline. The demo is free and takes 45 minutes.
