Depending on the industry, customer structure or internal processes, additional information is needed that a generic CRM or ERP solution does not provide out of the box – such as an internal customer category, a contract identifier or a special date that matters to the way you work. If software is maintained only through predefined standard fields, this extra information often ends up in separate Excel lists or free-text fields, where it can hardly be analysed in a structured way. 1Tool addresses this challenge with a flexible system of custom fields that can be applied to practically any module. This article explains how the system is structured and what it makes possible.",[14,15,17],"h2",{"id":16},"custom-fields-for-almost-every-module","Custom fields for almost every module",[10,19,20],{},"In 1Tool, practically any module – contacts or projects, for example – can be extended with your own custom data fields. Instead of settling for a rigid, predefined set of fields, companies can capture exactly the additional information that matters to their own processes. This is especially important when different departments or industries work with one and the same 1Tool installation and each needs different additional information on contacts, projects or other records. That way, the software adapts to how the company actually works, rather than processes having to be laboriously bent to fit the software. These fields are defined centrally, so they are then available to all authorised users and appear consistently in all relevant views and reports, instead of being visible in just one place. In this sense the software grows with the company, rather than being perceived after a while as too rigid or ill-suited to its own requirements.",[14,22,24],{"id":23},"seven-field-types-for-different-requirements","Seven field types for different requirements",[10,26,27],{},"So that custom fields genuinely match the kind of information they hold, 1Tool offers seven different field types: text (short), text (long), integer, decimal number, selection field (select box), multiple selection (list box) and date. Short and long text fields are suitable, for example, for notes of different lengths, integer and decimal fields for numerical values such as quantities or key figures, while select box and list box represent structured, predefined choices – the latter also when several values can apply at the same time. Date fields cover every case in which a specific point in time needs to be recorded, such as an internal reminder date. Thanks to this range of field types, a suitable format can be chosen for almost any additional piece of information, instead of, say, having to record a date as plain text or capture a choice as unstructured free text, which would make later analysis harder. Select boxes and list boxes in particular ensure that only the values actually intended can be selected when a record is entered, instead of every employee phrasing the same information differently. This consistency pays off above all when the captured values are later analysed in reports or filters, since inconsistently worded free-text entries would make clean analysis considerably more difficult.",[14,29,31],{"id":30},"structure-through-field-groups","Structure through field groups",[10,33,34],{},"The more custom fields a company creates over time, the more important it becomes to keep track of them. For this reason, your own fields in 1Tool can also be organised into field groups. Instead of a long, confusing list of individual fields, this creates a clearly organised structure in which related information is shown together. This not only makes maintaining the fields easier but also simplifies daily work for the employees who edit or view a record: related details are displayed together instead of being scattered among other, unrelated fields. For companies that capture many different kinds of additional information over time, this grouping is an essential building block for keeping the custom field system understandable and maintainable even years later.",[14,36,38],{"id":37},"frequently-asked-questions","Frequently asked questions",[10,40,41,45,48,49,52,54,55,58,60,61],{},[42,43,44],"strong",{},"Can I change or extend custom fields later on?",[46,47],"br",{},"\nYes, your own fields are managed centrally and can be adjusted or supplemented with further fields at any time.\n",[42,50,51],{},"For which modules can I create custom fields?",[46,53],{},"\nCustom fields can be set up for practically every module in 1Tool, for example for contacts or projects.\n",[42,56,57],{},"What is the difference between a select box and a list box?",[46,59],{},"\nWith a select box, users choose exactly one value from a predefined list; with a list box, as a multiple selection, several values can be selected at the same time.\n",[42,62,63],{},"What information is still missing from your CRM today because there is no suitable field for it?",[10,65,66],{},[67,68,70],"a",{"href":69},"\u002Fen\u002Fappointment-request\u002F","Book a demo",[14,72,74],{"id":73},"read-more","Read more",[76,77,78,85,91],"ul",{},[79,80,81],"li",{},[67,82,84],{"href":83},"\u002Fen\u002Fblog\u002Fcustom-form-views-drag-and-drop\u002F","The form builder behind custom contact views",[79,86,87],{},[67,88,90],{"href":89},"\u002Fen\u002Fblog\u002Finstant-search-settings-algolia\u002F","Type instead of click: Algolia instant search in the settings",[79,92,93],{},[67,94,96],{"href":95},"\u002Fen\u002Fblog\u002Fpdf-template-editor-html-css\u002F","HTML\u002FCSS editor for your own PDF templates with live preview",{"title":98,"searchDepth":99,"depth":99,"links":100},"",2,[101,102,103,104,105],{"id":16,"depth":99,"text":17},{"id":23,"depth":99,"text":24},{"id":30,"depth":99,"text":31},{"id":37,"depth":99,"text":38},{"id":73,"depth":99,"text":74},[107,108],3329,3330,"2026-04-28T09:00:00",false,null,"md","\u002Fmedia\u002F2026\u002F07\u002Fflexible-benutzerdefinierte-felder.jpg","en",{},"2026-07-25T08:31:27",true,"\u002Fen\u002Fblog\u002Fcustom-fields-every-module",{"title":5,"description":12},"Custom data fields for every module: seven field types and field groups in the 1Tool custom field system.","Custom data fields for every module in 1Tool","custom-fields-every-module","\u002Fen\u002Fblog\u002Fcustom-fields-every-module\u002F","en\u002Fblog\u002Fcustom-fields-every-module","posts","AYZVUmTNH6CwRGiz3QFlQymTgPnr01gZINzqJ9OM71k",1791582061087]
