180 modules. Whatever your process is, it is in here.

Estimating, tendering, BIM, quantities, programme, quality, safety, cash flow, site. Switch on the ones your job needs, leave the rest off, write your own.

Where the margin comes from.

One typical small/mid deal, broken down line by line. The open core stays free. Partners earn on the commercial layers and on services.

Services are 100% yours.

DDC writes the open core and doesn't quote implementation work. Every euro the client pays for partner hours, training or custom modules stays with the partner. No clawback, no marketplace fee.

One split on everything you resell from us: you keep 70%, we keep 30%. Same rate on licences, cost database, localisation packs, connectors and renewals. Your own services stay 100% yours.

100% implementation 70% localisation 70% commercial 70% recurring
Year-2 onwards: the same client pays an SLA / optimisation retainer. You keep 70% of that for as long as the client stays live. SMB volume compounds, ten live clients ≈ €21k/year before any new work.

Our partner program at a glance.

Standalone summary of what OpenConstructionERP's program offers. We deliberately do not publish side-by-side numeric comparisons with named vendor programs - their terms change, vary by region, and are best confirmed against each vendor's own public materials. Below is what we commit to in writing.

Figures reflect OpenConstructionERP's own partner agreement as published 2026-05-20. We deliberately avoid publishing side-by-side numeric comparisons with named vendor programs - their terms, regional minima and qualifying criteria change often and are best confirmed against each vendor's own public materials.

One partner deal. Same for everyone.

No tiers, no ladder, no certification gates. The same rate card from day one, whoever you are.

What the client is invoiced.

Your own work is one line and it is entirely yours. Everything you resell from us is its own line at the published price, and you keep 70% of it. Nothing is bundled, so the client can see what each thing costs. Below are the lines a partner invoice usually carries; anything else on the rate card works the same way.

Invoice line Client pays You keep
Implementation services Diagnosis, configuration, data migration, integrations, training and the first year of support.

70% to you

Two ways to price the licence line

Your agreement fixes one of them and it then applies to every client you bring. Either way you keep 70% of the line.

A
A royalty on your own fee The licence line is 15% of the implementation services on the same invoice. The CAD line and the licence line itself are outside that base.
B
A flat fee per deployment €1,250 to €3,000 to stand the system up, then €600 to €1,250 a year for support. Where you sit in the band follows the number of users.

The licence is charged on commercial deployments, meaning under your brand or with manufacturer support behind it. Delivering the plain open core with OpenConstructionERP attribution carries no licence.

What the 30% buys the client

The licence is not a fee for software the client could have taken for free. It is the manufacturer standing behind the core they are running.

  • Third line. Anything you and the client cannot resolve comes to the people who wrote it.
  • Releases, and compatibility of their configuration across them.
  • A clean legal footing for delivering the product under your brand.
  • For the CAD line, the engine's own yearly licence and support for new versions of each format.

Direct enquiries from your region come to you. We do not quote implementation work behind a partner.

How a deal runs, and what you own.

Every stage is paid, including the first. Nobody works for free to earn the right to quote.

Modules you build are yours

A module written for your market belongs to you. There are two things you can do with it, and both are fine by us.

Open
Give it to the open core Your licence royalty falls by 3 points for every module accepted, permanently, down to a floor of 5%. We take on keeping it working across releases. Your name stays on it.
Closed
Keep it to yourself The code stays with you. Each client running it buys a licence for that module, around €750 a year for a small firm and up by seat count. You sell it and keep 70%, and that licence also lifts attribution for that client. Keeping it working across releases is yours.

Three things the agreement asks

Short list, and none of it is a surprise later.

  1. Attribution until the licence is in force. Before that, the interface names OpenConstructionERP and keeps the copyright notices, on your public demo as well.
  2. A contribution agreement before your first commit. Code that depends on the licensed CAD engine does not go into the open core.
  3. Export control on the CAD engine. It falls under US export control, so before delivery into a given country, hosted or installed, we check and confirm which jurisdictions are open.

Reselling the CAD converters is its own short written agreement. It covers distributing them, not building on the engine.

What you actually get on day one.

Three concrete things: a 30-day timeline, a ready-made toolkit, and an honest map of where leads come from. No big promises, just the kit and the wiring.

First 30 days

Mostly async, light on calls.

  • Day 1-3 · Sign agreement (PDF, ~6 pages), Telegram invite, demo tenant credentials
  • Day 4-7 · Marketing kit handover (Loom walk-through, ~20 min, watch when it suits you)
  • Day 8-14 · Pick your first SMB target, async Q&A in Telegram, pricing review
  • Day 15-30 · Pilot proposal sent, listed in partner directory, eligible for inbound lead share

One 30-min call max in the first month - everything else is Loom, shared docs and Telegram. Built so a busy SMB consultant can onboard in evenings.

Marketing kit

Concrete assets, not vague support.

  • Branded demo tenant on demo.openconstructionerp.com/{your-name}
  • White-label sales deck (PDF + Keynote source) - your logo, your colours
  • Pricing one-pager per region (DACH, UK, US, FR, ES, IT, NL, RO, PL)
  • 3 ready-made BOQ templates per region (residential, small commercial, fit-out)
  • Email sequences for cold + warm outreach (3 variants, plain text)
  • LinkedIn & X co-marketing post templates with our hashtag set

Updated quarterly. Partners get a private GitHub release feed - new templates, decks and pricing land there as soon as they ship.

Where leads come from

Honest map of the funnel.

  • ~60-70% · Your existing client base - partners who already serve SMB GCs / subs / QS practices have the warmest path
  • ~15-25% · DDC inbound - directory listing routes enquiries to the closest partner
  • ~10-15% · Social co-promotion - DDC amplifies your case studies, posts and webinars across LinkedIn, X and YouTube (tens of thousands of AEC followers)
  • Bonus · Joint webinars and conference co-hosting once you have one live client

We can't replace your sales motion in Year 1 - but we can amplify it. Most first deals come from the partner's own network; DDC compounds from there.

What we won't do.

Anti-promises are honest promises. Here's what stays off the table:

×
We won't run your sales for you. Year-1 leads come mostly from your own network. We help, but we don't replace.
×
We won't gate the marketplace. No certification fees, no listing fees, no pay-to-play tiers. List as soon as you sign.
×
We won't invoice your clients without your sign-off. Resold or referred - you decide per deal, not us.
×
We won't change rate cards mid-deal. New rates only apply 90 days after notice, and never to deals already in flight.
×
We won't quote services against you. DDC has a written commitment to never compete on implementation, training or custom modules.
×
We won't hide the pipeline. If we route an inbound lead to another partner in your region, you'll see it in the partner Telegram - no surprises.

How to apply.

Four async steps, about two weeks end-to-end. Mostly your pace.

Apply

5-field form: name, company, country, website, current AEC clients.

Intro call

30 minutes, async-friendly (we'll do video or just trade Looms). We walk through your portfolio and target deals.

Sign & onboard

Partnership agreement (PDF, ~6 pages), Telegram invite, sales deck, demo environment, marketing kit handed over.

First deal

Listed on partner directory, co-promoted on our social channels, eligible for lead share from inbound enquiries.

Roughly 1-2 weeks end-to-end. Most steps are async - minimal calendar blocking on either side.

Common worries.

Plain answers to the questions worth asking before signing anything - ours, theirs, anyone's.

"What if you go out of business?"

The product is AGPL-3.0 open source. BOQ, BIM viewer, schedule, AI takeoff - everything sits on GitHub under a licence we can't revoke. If DDC disappears, your clients keep running, your contracts stay in force, and you can fork and maintain it yourself.

"What if I don't close any deals in Year 1?"

You owe nothing. €0 annual fee, no quotas, no minimums. You stay on the rate card indefinitely. There is no deal target.

"Can I exit and take my clients with me?"

Yes. Client contracts are between you and the client - DDC has no claim on them. Clients can keep running the AGPL build with nothing to renew. You'd just stop selling the commercial dual-licence and regional packs.

"What if you change the terms later?"

All partners get a rate guarantee on deals already in flight. New rates only apply to deals booked after 90 days' notice.

"Show me the contract before I commit."

The agreement is a 6-page PDF in plain English. We send it after the discovery call. No NDA required to read it. If anything looks off, you walk away - half an hour spent, no obligation.

"What if my first client hates the product?"

They run the AGPL build for free, so the downside is your hours and their time, not a five-figure licence locked in upfront. If a pilot fails inside 90 days, we run a joint retrospective and help you unwind it.

Still have questions?

Nine of them, answered straight.

It's AGPL-3.0 - can my client really use it commercially without paying anything?
Yes. AGPL-3.0 permits commercial use, modification, and self-hosting. The obligation is to publish derivative source code if you modify and distribute or expose it as a network service to third parties. For most construction firms running internally, no obligation triggers. For SaaS resellers or OEMs, a commercial licence removes the AGPL obligation entirely - that licence is one of the SKUs partners sell at 70% margin.
Why would a client pay a partner if the software is free?
For the same reason a developer pays a builder when bricks are sold at the merchant: assembling, sequencing, localising, validating, and operating the system reliably is the work. The repo gives you the bricks. The partner ships the building.
Will OpenConstructionERP compete with me on implementation services?
No. This is a written commitment in every partnership agreement. DDC's three commercial product lines are OpenConstructionERP commercial licences, CWICR (cost database), and cad2data converters - plus localisation packs and core training. Implementation services are 100% partner revenue. Where a strategic account asks DDC directly, we route it to the closest qualified partner.
How do margins actually pay out?
Two models, available per deal: (a) resold - partner invoices client at list, pays DDC the wholesale price, keeps the margin; (b) referred - DDC invoices client, pays partner the margin within 30 days of cash receipt.
Do I need to be a developer or a software house to qualify?
No. The dominant partner profile is a BIM consultancy or construction-tech integrator with one technical lead and one delivery lead. We help you onboard a developer if you don't have one - training is free for the first two engineers per partner.
What about CWICR - the cost database?
The community CWICR is free with the AGPL repo. The commercial CWICR - covering 11 countries, 55,000+ items, monthly updates, audit trail - is sold separately and resold by partners at 70% margin.
Can I run my client on the free AGPL version forever?
Yes - and many will. Partners earn their margin on the four things free AGPL doesn't deliver: production go-live, SLA support, localisation packs, and AGPL-free commercial licensing for clients who need it.
How is this different from being a mature cloud ERP partner?
Three concrete differences: (1) construction-native product (BOQ, IFC, schedule, AI takeoff), no retrofit; (2) higher margins, a flat 70% on everything you resell from us; (3) no annual partnership fee; (4) DDC explicitly does not compete on services.
What if I never close a deal - do I lose my partnership?
Nothing punitive. You stay on the rate card indefinitely. There's no demotion, no fee clawback, no expiry. If activity slows, we work with you on lead-share or co-sell.
