Kamakis-based Prime Tenders handles NCA, AGPO, eTIMS, TCC, EPRA and Kiambu County Single Business Permit registration for Ruiru bidders.
National systems — NCA contractor registration, AGPO certification, eTIMS and the KRA Tax Compliance Certificate (TCC) — apply the same way everywhere in Kenya. But a Ruiru or Kamakis business bidding on Kiambu County tenders has a few extra local requirements that a purely national checklist misses, and any one of them can get a bid rejected at the document check.
Under the Kiambu County Trade Licence Act, 2016, any business physically trading in Ruiru, Kamakis, or elsewhere in the county needs a Single Business Permit issued by the County Government of Kiambu — separate from your national Certificate of Incorporation or KRA registration. It’s one of the most commonly missed tender documents precisely because it doesn’t show up on a national checklist. We prepare and track your permit application alongside your national registrations, so nothing is left waiting on something else.
Alongside the national tenders.go.ke portal, Kiambu County posts its own tender notices on its county tenders page. Recent rounds have covered work sited specifically in Ruiru and neighbouring sub-counties — road, market, and street-lighting projects among them — so a locally registered contractor tracking only the national portal can miss opportunities sitting right on their doorstep. We track both sources, and our Daily Tender Alerts deliver matched notices straight to WhatsApp.
Under AGPO’s regulations, citizen contractors based and operating in a given region are given preference on procurement funded by that county government or other devolved funds. A Ruiru-based business bidding on a Kiambu County-funded project can therefore hold a genuine local edge over an outside bidder — provided the registration and compliance paperwork is in order. Public procurement across county and national entities is overseen by the Public Procurement Regulatory Authority (PPRA).
Tatu City Industrial Park’s manufacturers and its SME-focused Link Warehousing & Logistics Park are still expanding, and that construction and supply pipeline runs through NCA-registered contractors and AGPO-eligible subcontractors based nearby — not just national firms. Getting your registration in order early positions a Kamakis or Ruiru business to bid directly into the Tatu City pipeline. When you’re ready to bid, our tender preparation service takes it from registration to a compliant, submitted bid.
For anything that still needs an in-person visit — KRA PIN queries, business registration support — the nearest Huduma Centre serving Kamakis and Ruiru businesses is in Thika town. We handle most of this online on your behalf, but it’s worth knowing where to go if a query needs a physical visit.
Every tender starts with your core statutory documents. We prepare and file:
For construction, mechanical, electrical, and related works tenders — including the factory, warehouse, and infrastructure projects around Tatu City. We assess which National Construction Authority class (NCA1–NCA8) fits your project value and technical capacity, prepare the statutory and technical documents, and manage the application through to certificate.
AGPO unlocks the 30% of government procurement spend reserved for youth-, women-, and PWD-owned businesses, plus the added preference citizen contractors get on Kiambu County and devolved-fund procurement. We confirm eligibility, prepare ownership declarations, and handle the application.
Since KRA now validates tax returns against eTIMS data and rejects TCC applications from businesses that aren’t eTIMS-registered, we get this sequence right — eTIMS first, then a clean TCC — so your tender documents don’t stall at the last step.
For contractors and suppliers in energy, petroleum, and solar sectors — relevant to several manufacturers at Tatu City investing in solar-powered production — an EPRA licence is a precondition for bidding, not an optional extra. We prepare and submit the application and track it to approval.
We’re based in Kamakis ourselves, so we track both the national tenders.go.ke listings and Kiambu County’s own tender postings, and we know which county office handles what. Because registration and compliance sit alongside our tender preparation and tender account management services, we sequence your applications — eTIMS before TCC, business registration before AGPO, national registration alongside your county permit — so nothing stalls waiting on something else.

Yes. NCA, AGPO, and eTIMS are national systems, while the Single Business Permit is issued separately by the County Government of Kiambu under its Trade Licence Act, and is required for any business physically trading in Ruiru or elsewhere in the county.
It can. Citizen contractors based and operating in a given region are given preference on procurement funded by that county government or other devolved funds — so a Ruiru-registered business can have a genuine edge on Kiambu County-funded work, provided the paperwork is in order.
No — NCA registration applies specifically to construction, mechanical, electrical, and related works tenders. Supply and service tenders don’t require it.
Most procuring entities require a valid, already-issued Tax Compliance Certificate at submission — a pending application generally isn’t accepted, which is why we recommend applying well ahead of a tender deadline, not during it. Our tender preparation checklist lists every document to have ready before you bid.
Since 2026, KRA’s TCC applications are validated against eTIMS registration, so an unregistered business risks having its TCC application rejected outright — which then blocks it from any tender requiring a valid TCC.
Kiambu County publishes its own notices on its county tenders page, in addition to the national tenders.go.ke portal. We track both, and our Daily Tender Alerts deliver matched notices straight to WhatsApp.
