Bidflow

For electrical contractors and lighting distributors drowning in manual device counts, Bidflow is a breath of fresh air. Upload a PDF, wait under ten minutes, and get a CSV of every power device, light fixture, and control. The 95–99% accuracy claim holds up on clean drawings — we tested the sample project and it caught nearly everything. Corrections are easy: add or delete bounding boxes via the PDF viewer. The pay-as-you-go pricing ($0.03 per device) means you only pay for what you count, and volume users can rack up significant savings. Where it bites: the total lack of integrations. No API, no Accubid, no Bluebeam — you manually export CSV and import elsewhere. That friction adds up for firms with established digital workflows. Also, Bidflow only handles electrical: no mechanical, plumbing, or structural. If you need multi-trade takeoffs, you'll need another tool. The drawing complexity threshold also matters — highly cluttered or non-standard symbols can drop accuracy, and you'll spend more time correcting. Versus alternatives: Stack or PlanSwift are general-purpose takeoff tools with broader trade support and integrations, but they cost more upfront (subscriptions $150–$500/mo) and require manual symbol counting or setup. Bidflow wins on speed for pure electrical counts, but loses on flexibility. For electrical-only shops, it's a no-brainer low-risk trial. For multi-trade firms, it's a niche add-on at best. In practice, we'd use Bidflow for quick first-pass counts on large sets, then sanity-check and export. It's not an end-to-end estimating solution — just a faster way to get the numbers. The lack of an API limits automation possibilities, but for a $0.03/takeoff tool, you can't complain.
