Kerno vs MRPeasy
Comparison last checked October 10, 2026. Every figure comes from the two product records, each with its own sources and check dates.
The short answer
Pick Kerno if you are a formula maker who wants batch records, a QA stage and batch costing in a tool built around formulas, from $59.99 a month flat. Pick MRPeasy if you need purchase orders, dated planning and accounting or store integrations, from $49 per user a month; Kerno has no purchase orders or integrations today.
Choose Kerno if
- You work from formulas and want each batch to carry its QA criteria, with QA as a stage before completion.
- You want a flat price: Solo is $59.99 a month for one user and Teams is $149.99 for five.
- You do not need purchase orders, exports or integrations yet.
Choose MRPeasy if
- You need to know what to order and when: MRPeasy gives a requirement date and an action date per line.
- You raise purchase orders and want QuickBooks, Xero, Shopify or WooCommerce connected.
- You need serial numbers, from Professional at $69 per user; Kerno tracks at lot and batch level only.

| Accepts dated demandYou can tell it what is due and when, sales orders with dates, a forecast, or a production schedule. | PartialA batch can be assigned to a customer, and the Customers module holds companies with addresses. That is the whole demand side in the account: there is no sales order, no quantity due, no due date and no forecast anywhere in the menus, so the only date a batch carries is the one you type on it. The vendor's writing about an order layer with due dates describes something the account does not yet have, and its help-center article on forecasting demand still ends "This is a sample article", so it is not counted here. A customer record was opened on 2026-09-15 to be sure: it is a company with an address and named contacts, and it carries no order, no quantity and no due date.

| Nets against stock on handIt subtracts what you already have before telling you to buy more. | YesA batch lists what it needs, and each ingredient line opens a lot picker that shows every lot on hand with its stock and lets you assign a quantity against it; the section reads Needs Attention until the lines are covered, and stock on the lot falls by what was assigned. The dashboard carries an Inventory Stockout panel. That is requirements checked against stock on hand. The prototype's finished-goods view with Total, Reserved and Available columns was not found in the account, where Finished Goods is a list of product definitions, so read the netting as material-side. The vendor's pricing page lists "Inventory reservation and reconciliation" on the Solo tier, which matches the lot assignment seen here. This is the stock-on-hand half of the netting test; the other half, orders already incoming, is the gap, recorded under incoming orders.

| Counts incoming ordersIt knows about purchase orders and production orders already placed, so it does not tell you to order twice. | NoNothing incoming exists to count. A walk of every menu in the account found no purchase order, no expected receipt and no on-order quantity. The only inbound record is Add Inventory, which books stock that has already arrived with its vendor, lot number, purchase date, expiry date and cost. Kerno does not know what you have ordered until it is on the shelf. Kerno told us on 2026-09-15 that tracking incoming purchase orders is part of the v2 it is building now, which adds purchasing. No date was given, so this stays at no until an open order shows up in an account. Even then, tracking a purchase order is not the same as counting it in the plan: the netting test also needs an open order to reduce what a batch shows as short.

| Uses lead timesIt works backwards from when you need something to when you must order or start it, using supplier and production lead times. | PartialDates exist without lead times. Batches carry a creation date, a packaged date and an expiration date; lots carry a purchase date and an expiration date; production steps carry a planned duration. No ingredient, vendor or lot record has a lead time field, and nothing works backwards from a date. Every field on the three forms was listed on 2026-09-15: a vendor holds name, contact person, account number, email, phone, two addresses, country, state, city, ZIP, payment terms and website; an ingredient holds name, secret name, unit, notes, CAS number, form, category and hazmat; a stock receipt holds ingredient, SKU, vendor, lot number, purchase date, expiration date, cost, unit and quantity. Not a lead time among them. The dates are recorded, not used: nothing takes a required date and works out when to buy or when to start a batch, and a required-date workflow of that kind would pass this test without a lead time field.

The dashboard shows stockouts, batches in draft, batches pending QA, a production rate in batches per day and a Value at Risk figure; a batch section reads Needs Attention until its lines are covered.

| Capacity planningChecks whether your people and machines can do the work in the time available. | PartialThe dashboard reports Production Efficiency as a percentage, a rate in batches per day and a Workload Distribution by user, and Labor Costs define an operation, a resource such as a pouring station, and an hourly rate. Nothing compares planned work against available hours or refuses a batch the resource cannot do. The vendor's capacity worksheets are spreadsheets and name no Kerno feature.

| Production | ||
| Multi-level BOMSub-assemblies inside assemblies, a part that is itself made from other parts, nested as deep as you need. | NoOne level, with no way to nest. A product formula record holds a name, a product type and a SKU; the ingredient list lives on the batch, and the Add Ingredient picker there offers raw ingredients only, the three held in the account, with no product, formula or finished good among them. A base or premix that is itself made in a batch cannot be an ingredient of the next one, so a two-stage product is two unlinked batches.

| Recipes & formulasBatch-style production by weight, volume, or percentage, including scaling a batch up or down. | PartialBy weight and volume, yes; scaled, not that we saw. Ingredient lines carry a quantity and a unit (6.00 lb, 6.00 oz) and packaging a piece count, and the Product Formula record itself holds only a name, a product type and a SKU, with the ingredient, packaging, step and QA lists living on the batch and copied into the next batch of that product. Entering a different batch size did not change the quantities, and the definition here includes scaling a batch up or down, so this stays short of yes until scaling is shown. Retested on 2026-09-15: typing 12 into Batch Size on a draft built at size 1 left the lines at 6.00 lb and 6.00 oz, so a quantity is what the last batch of that product used, not a function of the size you enter. Retested again on 2026-09-23 in a new test business: a Soy Wax line entered as 5.00 lb stayed at 5.00 lb when Batch Size went from 10 to 20.

So a recipe scales in a straight line with batch size, and on Professional a fixed-quantity column adds components that do not scale.

| Routings & operationsThe ordered steps a product goes through, and which machine or station does each one. | YesNumbered production steps with an operation, a planned duration, an hourly rate, a description, an operator and a status, copied from the product into each batch. The Labor Costs page defines each operation against a resource, for example Pour on the pouring station at $20 an hour, so a step does name the station that does it.

| Quality controlsChecks, tests, holds, and non-conformance records tied to production or receiving. | YesEach batch carries QA Requirements as criteria, standard and status, for example Cold throw, scent noticeable at 12 inches after 48 hours cure, Approved. QA sits as its own stage between In Progress and Completed, is marked Required before completion, and a failed batch goes to Denied, which the dashboard costs separately.

| Expiry & shelf lifeBest-before dates on materials and finished goods, with warnings before they lapse. | PartialDates are recorded and nothing acts on them. Every lot receipt takes an expiration date and every batch carries one (the completed batch shows Aug 2027), and the lot picker displays a lot's expiry beside its stock while you assign it. No warning fires before a date lapses and nothing blocks an expired lot from being assigned. The vendor's soap guide confirms the shape: Kerno keeps the dates and "the soap maker remains responsible for deciding".

| Product costing & COGSWhat it costs you to make one, and the cost of the goods you sold. | YesA completed batch shows raw material, labour and packaging cost and a total, here $21.30, $15.00 and $10.20 for $46.50, with a cost per finished unit and retail and dealer prices set as a percentage over cost. Labour comes from the step's duration times the operation's hourly rate. Account Settings choose average cost or a specific vendor's cost for ingredients, average or per-SKU cost for packaging, and whether an electricity rate enters batch cost. The vendor's guide states the method: "Recorded cost per acceptable unit = recorded batch input cost ÷ acceptable finished units".

The account has no connector, AI or integration settings, and the help center's "Integrations & AI" category was empty on 2026-09-23. Kerno has not been asked directly. Checked in an account on 2026-09-23, on the site owner's login, including a new test business set up from scratch; the app pages cited need a login, and an account of your own reproduces them. | YesMRPeasy runs its own MCP server: "The server exposes every API v2 GET endpoint as a tool, giving the model read-only access to your manufacturing data." Read access meets our definition (read or act). Scope: read-only, it cannot create or change records, and it authenticates with an API key, which the pricing page puts on the Unlimited plan ($149/user/month, minimum two).

| CSV exportYou can get your lists out as spreadsheet files. | NoFour lists import and none exports. Vendors, Customers, Finished Goods and Labor Costs each offer Import CSV with a downloadable template, which is a real convenience for loading a shop. No list in the account has an export control, the Export button seen in the prototype's reporting area was not found, and the vendor's own guide for new users tells them to ask whether "the business export items, formulas, inventory, and production history in a usable format". Kerno confirmed on 2026-09-15 that CSV export does not exist yet and said it will add it to the roadmap, with no date. Until it ships, assume your data leaves by hand.

| Full data exportYou can take everything, including history and relationships, not just a few screens' worth of rows. | NoNothing in the account exports anything, and the Profile page's only bulk action is Delete Account, which the page says will "permanently remove all your shops and data". We asked Kerno on 2026-09-15 and it is checking internally, with an answer to follow. Until then, ask the vendor before you load real history.

The user manual: "You can download your database backup file to your computer and keep a copy," and "The MRPeasy database backup file can be used/read only in MRPeasy." A restore needs a file that is "not older than 30 days" and "downloaded from the same account it is restored to", and it erases the current database. So it protects you inside MRPeasy; it is not a portable export for leaving. List-level CSV export is recorded separately. The pricing table ticks "Database backups" on all four plans.
