Short answer
A bespoke perfume — one made for a single client — needs the same formula records as any product, plus a client file: the consultation notes and brief, every sample shown and the client's reactions, the approved formula version, the concentration and format, and the agreement about ownership and reorders. Because the client file holds personal information, possibly including skin sensitivities or allergies, collect only what you need, ask for consent, store it securely, and follow the data-protection rules that apply to your clients. With good records, a reorder five years later smells the same as the first bottle.
What makes bespoke work different
- One client, one formula — or a few formulas per client over time.
- Reorders come years apart, long after you have forgotten the details.
- The client's words drive development, so they must be recorded faithfully.
- Personal information sits next to the formula.
The client file
| Section | Contents |
|---|---|
| Client | Name and contact, client code, consent record, how they prefer to be contacted |
| Consultation | Date; preferences and dislikes; reference perfumes; occasions; format and strength wanted; any sensitivities the client chooses to share |
| Brief | Your translation of the consultation into a formulation brief |
| Submissions | Each sample's number and formula version, date given, the client's reaction in their own words, your interpretation |
| Approval | The approved formula code and version, concentration, format, date |
| Production | Each bottle made: batch code, date, quantity |
| Agreement | Price, ownership of the formula, exclusivity, reorder terms |
The brief and submission parts follow the same pattern as commercial development; see how to write a fragrance brief and fragrance mod and sample tracking.
Linking client and formula
Give each bespoke formula a code that connects it to the client file without exposing the client's name in the formula library — for example a client code in the formula's tags or notes. Anyone working on the formula sees the code; only the client file maps it to a person. This keeps the library searchable and the personal data contained.
Personal information
- Collect only what you need to make the perfume and contact the client.
- Tell clients what you keep and why, and get their agreement — in writing or by a recorded statement.
- Treat health-related information, such as allergies, with particular care; ask only if it affects what you make, and record it only with consent.
- Store client files securely, separately from shared lab notes, and restrict access.
- Decide how long you keep client files, and delete them when that period ends or the client asks, subject to any records you must keep for product safety.
Data-protection laws vary by country and some apply to clients wherever you are; if you serve clients in the EU or UK, for example, their rules on personal data apply. Take advice if you are unsure.
Safety and the product
A bespoke perfume sold to a client is a cosmetic product like any other in most markets, with the same expectations for safety, restrictions and labeling. A client's request does not change the limits for restricted materials; see how to calculate IFRA compliance. If a client tells you about an allergy, take it seriously — but you cannot promise a perfume will not cause a reaction.
Reorders
- Find the approved formula version from the client file.
- Check every material is still available in the same grade; if not, plan and test a substitution and tell the client.
- Recheck restrictions against the current standards — they may have changed since the first order.
- Make the batch, compare with a retained sample if you kept one, and record the new batch in the file.
Version control is what makes this reliable; see perfume formula version control. Where bespoke work sits in a fragrance business is covered in the fragrance development workflow.
Frequently asked questions
Does the client own a bespoke formula?
Only if you agree that they do. Many bespoke perfumers keep the formula and promise exclusivity or reorders instead. State it in the agreement; see who owns a perfume formula?
Should I keep retained samples for bespoke clients?
Yes, a small one per batch. It is the only way to check that a reorder matches.
