Two firms, one desk

Authored by Zatra, built by NEMBO.

Zatra Consultants Limited is a Tanzania business incorporation, compliance and investment advisory consultancy at Mwenge Tower, Sinza A, Dar es Salaam. It writes and checks the content. NEMBO designs, builds and delivers it. One brief reaches both.

Pick the situation

Start from the pain, not the product.

Six situations. Each shows the pain, the worry, the relief, the time, the cost served and the revenue boost, with the documents that answer it.

The pain

The bank, the buyer or the tender has asked for a document the company does not have, and the week goes to paperwork instead of customers.

The worry

Being turned down for looking unready, when the business itself is sound.

The relief

The owner shares the facts already held. Zatra Consultants writes and checks, NEMBO designs and delivers one matched set: plan, profile, letter, invoice.

Time

Short documents in under 30 minutes, as a target. Research documents on a date set by scope.

Cost served

One production desk in place of a writer, a designer and a reviewer. Target: cost down by up to 75%.

Revenue boost

A ready file reaches the lender, buyer or panel sooner, so the decision is made sooner.

Typical rejection: A plan returned for missing evidence, a profile that does not show standing, a quote that is not answered.

Business plansInvestor documentsLetterheadsInvoices

Time, cost and sales figures are service targets set against the Client's own baseline and stated in the written quote. They are not guarantees.

Rejections handled

Questions

What clients ask first.

What is NEMBO?

NEMBO is the trading name of Nembo Creative Limited in Dar es Salaam. With Zatra Consultants Limited it writes, checks, designs and delivers finished professional documents from the details a Client shares: invoices, letters, plans, investor documents, financial reports, books and campaigns.

Are samples or templates sold?

No. The Client shares the details and receives a finished document written on the Client's own facts. The pages shown on this site are specimens on fictional companies, shown to prove the finish.

How fast is a document delivered?

Short documents are targeted at under 30 minutes from complete details, standard documents follow in hours, and research documents are dated in the written quote.

What if a bank, a panel or an officer rejects the document?

The rejections table shows who rejects, why, and what each document carries to prevent it. A returned document is reviewed against the same tests.

Does the desk compete with accountants, lawyers or consultants?

No. They can refer, co-deliver, share overflow or hand over. The adviser keeps the client.

Who writes the content?

Zatra Consultants Limited authors and checks. NEMBO designs, produces and delivers.

How is payment taken?

Against a written quote and a pro-forma invoice, through Pesapal on its own secure page: M-Pesa, Tigo Pesa, Airtel Money or card.

Ready when the brief is.

Replies are targeted within four working hours. The price is on this site; the only thing left to agree is the start date.
