- Included in the Serenity plan, for every payment request.
- Included at the end of each stage in stage-by-stage monitoring.
- With the Essential plan: 20,000 CFA francs (about €30) during a visit already planned.
- With a dedicated visit, or ordered on its own: 50,000 CFA francs (about €76).
- Answer within 48 hours of the builder's request.

Site on hold? Pause your plan
A transfer running late, the rainy season: sites often stop. Your monthly plan is then suspended on a simple message.
While work is stopped, a monthly surveillance visit checks the condition of the site, the materials and the stock, and you receive the report, for 20,000 CFA francs per month (about €30). Restarting is free of charge.
05
Your house is finished
The end of the works is when attention drops, and when the last payment is at stake.

What the price of monitoring represents
One month of Bon Œil monitoring costs the same as a few dozen bags of cement. A single undetected problem costs millions. For a twelve-month Standard project, the Serenity plan represents between 2% and 6% of the building budget.

Image IAOne month of monitoring, in building materials
| Monthly plan | 50 kg bags of cement | 15 cm concrete blocks | 12 mm steel bars | Painting, supplied and applied |
|---|---|---|---|---|
| Essential Compact (60,000 CFA francs) | 15 | 170 | 9 | 30 m² |
| Essential Standard (75,000 CFA francs) | 18 | 215 | 12 | 38 m² |
| Serenity Compact (115,000 CFA francs) | 28 | 330 | 18 | 58 m² |
| Serenity Standard (150,000 CFA francs) | 37 | 430 | 23 | 75 m² |
What an undetected problem costs
| Common situation | Your loss | Equivalent in months of Serenity Standard |
|---|---|---|
| 10 bags of cement diverted every week | about 164,000 CFA francs per month | More than a month of monitoring lost every month |
| Quote inflated by 10% on a 40 million CFA francs project | 4,000,000 CFA francs | 27 months |
| A 3 million CFA francs payment request paid for a stage not completed | 3,000,000 CFA francs | 20 months |
| Slab to be demolished because of faulty reinforcement | Often several million CFA francs, plus months of delay | Several years of monitoring |
Indicative figures, based on average prices in Lomé: 50 kg bag of cement at about 4,100 CFA francs (a tonne of cement sells for around 80,000 CFA francs to 81,000 CFA francs in Togo according to L'Économiste du Faso), 15 cm block at about 350 CFA francs, 12 mm steel bar at about 6,500 CFA francs, painting supplied and applied at about 2,000 CFA francs per m².

Secure payments through a notary escrow
Your money stays with the notary until you decide to pay.

- An agreement signed between you, the builder and the notary
How it works
- Signature of the escrow agreement with the notary and the builder.
- You top up the account as you make transfers.
- Whenever a payment is requested, Bon Œil checks the stage on site and sends you its report.
- Based on that report, you yourself instruct the notary to pay, and the notary then pays the builder.
What you receive
An inspection report before every payment decision.
Price
- Notary's fees paid directly by you; Bon Œil coordination on quotation
Net prices, no VAT.
Good to know
Your money is held by the notary, never by Bon Œil or the builder. Bon Œil informs you; the decision to pay and the instruction to the notary always remain yours.
