Why process plants need chemical ERP software
Chemical manufacturing does not fit the assembly-line model that most business software is designed around. Raw materials arrive in tankers, drums, IBCs and bags, with purity that varies from lot to lot. Recipes scale with batch size, reactions yield more or less than planned, solvents are recovered and reused, and some batches produce useful by-products. Chemical ERP software is designed for this kind of batch process, where quantity alone does not describe the material.
DotOne is the system we configure for specialty chemical, paint, adhesive, resin, agrochemical formulation, dyes and intermediates manufacturers and chemical traders. It holds stock by batch with its quality attributes, converts between kilograms, litres and active content, controls QC release and links every finished batch back to the raw material lots used in it.
Formulations, recipes and batch scaling
The formulation is the core intellectual property of a chemical business. In the ERP, each product has one or more recipes defined for a standard batch size, with ingredients, quantities, order of addition and process parameters such as temperature, pH, pressure and hold time. Recipes are version-controlled, so changes are approved and recorded, and older versions remain available for reference.
When a batch is planned, the recipe scales to the planned batch size and the reactor or vessel capacity. Where an ingredient is purchased at a different concentration from the recipe basis, the quantity is adjusted for the actual assay of the lot being issued. Access to formulation details can be restricted by role, so the shop floor sees what it needs to charge without exposing the full recipe.
Units, density and assay-based stock
Chemical stock is measured in several ways at once. A solvent may be bought in kilograms by tanker, stored in a tank measured by dip in litres and issued to the reactor by flow meter. An acid may be bought at one concentration and consumed on a 100 percent basis. A pigment may be valued on its active content.
- Unit conversions using specific gravity or density, configured per item and optionally per lot.
- Assay or purity recorded per lot from the incoming test, with stock reported both as received and on an active basis.
- Tank stock from dip readings converted to kilograms, with variances recorded as gain or loss.
- Container tracking for drums, carboys, IBCs and bags, including returnable containers held by customers.
- Tare, gross and net weights captured at packing and dispatch.
This makes stock valuation and consumption reporting reliable, which is hard to achieve when conversions are done on a calculator each time. The inventory management setup covers multi-unit stock in more detail.
Reactor batches, yield and solvent recovery
Each production batch in the ERP has a batch number, the vessel or reactor used, the recipe version, the raw material lots charged with their quantities, and process readings at the stages you choose to record. At the end of the batch, output is recorded with its yield against the theoretical yield, and in-process or final samples are sent to QC.
Yield and losses
Yield is reported per batch, per product and per reactor, with reasons for low yield recorded. Over time this shows whether a particular raw material supplier, reactor or shift is associated with lower yield.
Solvent recovery
Solvents recovered by distillation are booked back into stock as recovered solvent with their own quality and value, and recovery percentage is tracked. This reduces purchase of fresh solvent and gives a true net solvent consumption figure.
By-products and co-products
Where a process yields saleable by-products or co-products, they are recorded as output with their quantity, and batch cost can be apportioned between main and secondary products using the method you choose.
Rework and reprocessing
Off-spec batches can be reworked, blended or downgraded. The ERP links the rework batch to the original so the history and the cost stay together.
Quality control, COA and batch release
In chemicals, a batch is not finished until QC releases it. We configure test specifications per product and per raw material with parameters, methods and acceptable ranges. Incoming lots are held in quarantine until tested, and production batches are held until QC approves them. Stock under test or rejected cannot be issued or dispatched.
When results are entered, the certificate of analysis is generated from them in your format, ready to send with the dispatch. Retest dates and shelf life are tracked per batch, so material approaching its retest date is flagged before it is used or sold. Batch genealogy from finished goods back to raw material lots is held in the batch traceability module, which helps when a customer raises a complaint.
Safety, storage and documentation
Chemical plants store flammable, corrosive and toxic materials that are subject to storage limits and handling rules. The ERP can hold hazard classification, storage conditions and safety data sheet references on each item, and show stock by storage area so that quantities stored in a licensed area can be monitored against the permitted limits you set.
Labels for drums and bags can carry product, batch, net weight, hazard information and handling instructions from the item master. Dispatch documents can include the transport emergency information you need for hazardous consignments. These records help plants respond to inspections and customer audits without searching through paper files.
Batch costing and price revision
Chemical margins are sensitive to raw material prices, many of which track crude oil, natural gas or international commodity markets. DotOne calculates batch cost from actual raw material lots at their cost, adjusted for assay, plus utilities such as steam, power and cooling, reactor time, labour and overheads, less the value of recovered solvent and by-products.
Cost per kilogram is reported by batch and by product, and estimated costs for quotations update from current purchase rates. This supports timely price revisions with customers when key raw materials move. More detail is on our costing software page.
Customers, toll manufacturing and dispatch
Chemical businesses sell to industrial customers on contracts and scheduled orders, through distributors, and sometimes manufacture for other companies on a toll or job work basis using customer materials. The ERP manages customer-specific specifications and COA formats, price lists linked to raw material indices where agreed, and credit control.
For toll manufacturing, customer materials are held as customer stock, consumed against the customer batch, and the output is returned with a reconciliation of materials and yield, with only conversion charges billed. Dispatch documents list containers with batch and weights, and GST e-invoices and e-way bills are generated from the same transaction. Returnable drums and IBCs are tracked by customer until they come back.
What is the best ERP for the chemical industry?
When comparing chemical ERP software, focus on process fit. Ask the vendor to receive a raw material lot with an assay, scale a recipe to a non-standard batch size, charge the reactor with assay adjustment, record yield and solvent recovery, hold the batch for QC, generate a COA and dispatch in drums with tare and net weight. Systems that cannot do this without workarounds will push the real work back into spreadsheets. Our guide on how to choose ERP software lists further evaluation points.
