Stop pouring your margin into the mixing cup

Keepsel is inventory and production software for resin artists. Measure resin and hardener by the ounce, cost pigments, molds and hardware into every cast, and price each piece from its true numbers, including the waste every pour leaves behind.

Built around how resin artists actually work

Mix ratios are money math

A 2:1 pour that needs 0.9 oz of mixed resin costs a knowable amount, until cup residue, overpour and the odd failed cast eat into it. Build a waste allowance into each recipe so pricing matches reality.

Molds wear out, and someone has to pay for them

A $14 silicone mold good for ~80 casts adds about 18¢ to every piece. Put a share of the mold in your recipes and the replacements fund themselves instead of surprising you.

Pigments, glitter, inclusions: the tiny costs multiply

Mica, dyes, foils and dried flowers are cheap per gram and expensive per year. Tracking them in the recipe turns 'a pinch of glitter' into a real line item.

Every color is its own product

Ocean blue, galaxy purple, gold-flake clear: each colorway and shape sells differently. From the Maker plan, each can be a variation with its own stock, and Suli can tell you which combinations actually move, so you pour more winners.

A day in Keepsel, for resin artists

Load your resin bench
Resin and hardener by the ounce, pigments by the gram, hardware and molds by the piece, all at real prices.
Cast a batch
From the Maker plan, a work order for twelve keychains deducts the mixed resin, pigment, hardware and a slice of mold life, and adds twelve finished pieces to stock (work orders up to 10 a month on Maker as a trial and 100 on Team, unlimited on Business and Enterprise).
Price by the cast, not the vibe
Each shape and colorway carries a true cost, so customs and markets are quoted from numbers, not nerves.
Reorder ahead of the next pour
From the Maker plan, alerts on resin and your go-to pigments fire before a weekend of orders meets an empty bottle.

Worked example

Resin Keychain, costed line by line

This is the math Keepsel does for every product you make: every line from its recipe, updated whenever a material's price changes.

The waste allowance and mold line are what separate a real resin cost from a hopeful one.

Questions resin artists ask

How do I price resin art pieces?

Cost the mixed resin your piece actually consumes (waste included), add pigments, inclusions, hardware, a share of mold life and your time, then set margin on top. Small pieces often price at 4–6× materials; large statement pieces are mostly labor.

How much resin does a piece really use?

More than the mold volume: cup residue, stir sticks and overpour typically add 10–20%. Weigh a few pours, set that as the recipe amount, and your remaining-resin count will finally match the bottle.

How do I account for failed casts and seconds?

Bake an expected failure rate into your waste allowance, and count genuine failures out of stock so your materials stay honest. Sellable seconds can become their own discounted product instead of disappearing from the books.

Can I track dozens of colorways and shapes?

Yes. From the Maker plan, color and shape can be variations, so a keychain in eight colors is one product with eight combinations, each with real cost and stock.

Does resin inventory tracking work for custom orders?

Customs quote cleanly when the recipe exists: you know the resin, pigment and hardware cost before you answer the DM.
