How Software Development Shops Can Win Public Business RFPs Without Losing Margin to Middlemen

Most boutique software shops have the same complaint: there's no shortage of RFPs out there, but the good ones are buried behind aggregator subscriptions, gated procurement portals, or referral middlemen who skim 15–25% off every contract they pass along. By the time the work reaches your inbox, the margin is already gone.

This piece is for the founders and BD leads at small-to-mid software development agencies — the 5-to-50-person shops doing custom web apps, mobile builds, integrations, DevOps, or niche vertical SaaS — who want to respond to public business RFPs without giving up a chunk of every deal to a platform that didn't write a single line of code.

The real economics of chasing public RFPs

Let's be honest about what it actually costs to chase an RFP today. A typical sales-qualified RFP response for a £40k–£250k custom build will burn somewhere between 8 and 30 hours of senior time: reading the spec, asking clarifying questions, scoping, writing the proposal, costing it, and presenting. That's before you've won anything.

Now stack the platform costs on top:

• Subscription-based RFP aggregators: £200–£2,000/month, often with tiers that gate the bigger contracts
• Lead-gen marketplaces: 10–20% commission on awarded contracts
• Procurement consultants and brokers: flat finder fees or ongoing percentages
• Marketplaces that lock communication inside their messenger so you can't talk to the buyer directly until you've paid

For a 12-person agency winning four mid-sized contracts a year, that overhead can easily eat £30,000–£60,000 — money that should have funded a senior hire or a sales engineer.

Why the commission model is especially brutal for dev work

Software projects have long tails. A custom build leads to maintenance, a phase-two scope, integrations, then a managed services retainer. When a marketplace takes a percentage of "originated revenue" for the lifetime of a client relationship, you're essentially paying rent on a client you now service entirely yourself. That's the bit that quietly destroys agency economics.

What public RFP buyers actually want from a dev shop

Before we talk channels, it's worth remembering what the person on the other side of the RFP is actually trying to solve. Public business RFPs — whether from a logistics company needing a TMS integration, a charity replatforming its donor database, or a manufacturer wanting an OEE dashboard — share the same anxieties:

1. Will this shop understand our domain, or will we be paying them to learn?
2. Can we talk to a human quickly, not wait three days for a portal message?
3. Is the quote real, or will it balloon at change-request time?
4. Can we see comparable work without it being NDA-redacted into uselessness?
5. Are we going to be locked into a platform or escrow we don't control?

If you can address all five in your first response, you're already ahead of 80% of bidders. The fifth one — buyer reluctance to be locked into a platform — is exactly why direct, low-friction channels are increasingly winning over commission-heavy marketplaces.

A leaner way to respond to RFPs

This is where ZeozGig fits into the picture. It's a zero-commission B2B marketplace where buyers post RFPs and suppliers respond — but the economic model is flipped. Instead of taking a percentage of your awarded contract, ZeozGig charges small fixed fees per action: £1 to list a service, £5 to open a direct connection with a buyer, £0.50 for a voice call, £1 for video. No subscriptions. No commission. No lifetime revenue share.

For a software shop, that means:

• You can list your core service offerings (e.g. "Laravel API development," "React Native mobile builds," "Azure DevOps migration") permanently for a one-off £1 each
• When a relevant RFP appears, opening a direct line to the buyer costs £5 — not 15% of the eventual contract
• You can jump from chat to a discovery call without leaving the platform or paying a per-minute toll
• If a buyer posts an RFP and gets zero responses, their fee is refunded automatically — which keeps the buyer pool serious and active rather than fishing

Where this matters most in the dev sales cycle

The expensive moment in any software RFP isn't the proposal — it's the first qualification call. That's where you find out whether the spec is realistic, whether budget is real, and whether you actually want this client. On commission-based platforms, agencies delay that call because every conversation feels like it might trigger a future revenue cut. On a fixed-fee model, you call early, qualify hard, and walk away from bad fits without guilt.

Practical playbook for the next 30 days

If you run BD for a dev shop and want to stop bleeding margin to middlemen, here's a concrete plan:

1. Audit your current RFP channels. Add up subscriptions, commissions, and finder fees from the last 12 months. Most agencies are shocked.
2. List your three or four highest-margin service lines on a zero-commission marketplace like ZeozGig. Be specific — "Shopify Plus B2B migration" pulls better than "ecommerce development."
3. Set a response SLA. Be the first dev shop a buyer hears from. On direct-connection platforms, speed compounds because the buyer hasn't been bombarded by 40 templated replies.
4. Qualify on a voice call, not a written proposal. Fixed per-call fees make this economic.
5. Track win rate by channel, not just volume. A channel that produces fewer but higher-margin wins is usually the one to double down on.

Keep what you earn

The agencies that will quietly do best over the next few years aren't the ones bidding hardest on the loudest platforms — they're the ones removing parasitic costs from their sales pipeline so every won deal actually contributes to the bottom line.

If you run a software shop and you're tired of paying commission on clients you service yourself, list your services on ZeozGig for £1, or browse open RFPs and connect directly with buyers for a flat £5. No subscriptions, no contracts, no percentage of your hard-won contracts. Just the work, the client, and the margin you actually earned.
